The Effectiveness Of Physical Therapy And Rehabilitation Approaches In Low Back Pain On Pain Severity And Disability; A Systematic Review

Abstract

Low Back Pain encompasses nociceptive pain, neuropathic pain radiating to the legs, and nociplastic pain, often classified as non-specific due to central nervous system exaggeration. Globally, Low Back Pain is a leading cause of activity restriction and loss of productivity, significantly impacting finances. Objective; This study aimed to review the efficacy of physical therapy and rehabilitation approaches for LBP, focusing on pain intensity and disability. Materials and Methods; A literature review was conducted in PubMed and Web of Science databases up to January 30, 2024. English studies were required, using keywords: “low back pain,” “pain intensity,” “pain severity,” “disability,” and “physical therapy.” Pain intensity was measured using the Visual Analog Scale (VAS) and Numeric Rating Scale (NRS), including the 11-point Pain Intensity Numerical Rating Scale (PI-NRS). Disability was assessed using ADL, IADL scales, Roland Morris Disability Questionnaire (RMDQ), and Oswestry Disability Index (ODI). Results; Seven study met the inclusion criteria from 665 initial records. Interventions included osteopathic manipulative treatment (OMT), core muscle exercise with interferential current (IFC), cognitive functional therapy (CFT), dry cupping therapy, high-intensity machine-based core muscle resistance training (C-IPU), heat therapy, TENS, pelvic traction, Reiki, dynamic muscular stabilization technique (DMST), and McGill Big 3 (MB3). Sample sizes ranged from 30 to 1090 participants. IFC combined with core muscle exercises significantly reduced pain intensity compared to each method alone, though not statistically significant (p > 0.05). The C-IPU group had greater pain relief (P 0.05). Dry cupping did not outperform sham cupping. CFT reduced absenteeism in the first two years but not later. Reiki showed significant improvement in pain and ADL compared to drug therapy, but not to physiotherapy. Conclusions; Physical therapy interventions effectively alleviate symptoms and improve outcomes in LBP. However, variability in interventions and outcome measures necessitates cautious interpretation. Further research with standardized protocols is essential to understand the effectiveness and optimal duration of physical therapy for LBP.
